我正在开发spring-hibernate-jsf应用程序,但我不理解managedbean和spring控制器之间的区别.我认为管理员就像控制器一样工作.使用controller或managedbean有什么好处吗？

After successfull login, it doesn't redirects to "index.php". It redirects same page which is "login.php". Is there something wrong with my spring-security.xml page?

顺便说一下,当我运行应用程序时,它会将我重定向到"login.php",这很好.但它没有显示primefaces组件,但显示html组件.在我成功登录后,它重定向同一页面,但这次它显示的是Primefaces组件而不是html组件.

我的登录页面

我尝试运行项目时收到"class file functionContext not found"错误.它运行没有错误,但在我写了一些单元测试并删除它后它开始给出这个错误.这是错误堆栈跟踪;

编译错误:

我想做的是; 当用户点击行时,它将选择行.当用户双击行时,它将开始单元格编辑.在Primefaces展示(http://www.primefaces.org/showcase/ui/d ... nstant.jsf),它说"即时行选择,dblclick选择和取消选择是使用ajax行为实现的." 但我无法找到他们实施dblclick选择的地方.有没有办法用双击事件启动单元格编辑事件？

我有一个commandButton和一个对话框.问题出现在对话框出现后,它会消失(1-2毫秒后).我的命令按钮或其对话框问题有问题吗？

<p:commandButton id="showDetailsButton"
     title="Details"
     onclick="details.show();"
     process="@this"
     update=":tabView:myForm:myDialogId"                                         
     icon="ui-icon-search">                          
</p:commandButton>


<p:dialog id="myDialogId"
      header="Details"
      widgetVar="details"
      resizable="false"
      height="600"
      width="450"                  
      >
//some stuff
</p:dialog>

我收到"java.lang.UnsupportedOperationException:未实现延迟加载." 错误.当我对项目进行debub时,lazyModel的构造函数正在运行,但是不执行load方法.

我的xhtml页面;

<p:dataTable id="envelopelistid" var="envelope"
                     value="#{incomingEnvelopeListController.lazyEnvelopeDataModel}"
                     selection="#{incomingEnvelopeListController.selectedEnvelope}" selectionMode="single"
                     rowKey="#{envelope.instanceIdentifier}"
                     sortMode="multiple"
                     lazy="true"
                     style="min-height: 300px"
                     paginator="true"
                     paginatorTemplate="{RowsPerPageDropdown} {FirstPageLink} {PreviousPageLink} {CurrentPageReport} {NextPageLink} {LastPageLink}"
                     rowsPerPageTemplate="5,10,15"
                     rows="10">

我的控制员;

private LazyDataModel<Envelope> lazyEnvelopeDataModel;

public void init(){
...
lazyEnvelopeDataModel = new LazyEnvelopeDataModel(genericService,envelope);
}

我懒惰的数据模型;

@Override
public List<Envelope> load(int first, int pageSize, String sortField, SortOrder sortOrder, Map<String, String> filters) {

    if (sortField == null) {
        sortField = "identificationId";
    }

    datasource = genericService.getByTemplate(envelopeModel, first, pageSize, new Order(sortField, Order.convertSortOrder(sortOrder.toString())));
    setRowCount((int) genericService.getCountByTemplate(envelopeModel));
    return datasource;


}

我对服务有点困惑.为什么我必须使用服务进行hibernate集成？我想我可以直接使用DAO接口.例如,在本教程http://www.onlinetechvision.com/?p=566为什么他使用IUserService而不是IUserDAO.IUserService真的有必要吗？

我有关于primefaces数据表的问题.如您所见,列边框和标题存在对齐问题.这是一个主要的错误或我的数据表有什么问题？顺便说一句,数据表有动态列.

<p:dataTable     scrollable="true" scrollWidth="100%" editable="true" editMode="cell"   
var="invoiceLine" value="#{myController.invoiceLines}"                          
                         selection="#{myController.selectedInvoiceLine}" selectionMode="single" rowKey="#{invoiceLine.uuid}"
                         >
<p:columns value="#{myController.columns}" var="column"
                           styleClass="ui-editable-column" width="50"
                           columnIndexVar="colIndex">

//some stuff
</p:columns>         

            </p:dataTable>

我找到了一些解决方案,但没有一个能为我工作.下面的代码给出

"Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Unsupported configuration attributes: [admin]" 

错误.当我将auto-config属性更改为"true"时,再次给出相同的错误.

<http auto-config="false">
    <intercept-url pattern="/pages/login.xhtml*" access="IS_AUTHENTICATED_ANONYMOUSLY"/>
    <intercept-url pattern="/**" access="admin" />
    <form-login login-page='/pages/login.xhtml' default-target-url="/**"
                authentication-failure-url="/pages/login.xhtml"/>
    <logout logout-success-url="/pages/logout.xhtml" />
